Review
The Goodman 5-ton downflow system represents a practical middle ground for homeowners balancing performance and budget. At 100,000 BTU heating capacity and 97% AFUE, this furnace dominates the heating side of the equation, making it especially compelling in northern climates. The unit weighs 73 pounds, fits tight spaces with its 21x21-inch footprint, and accepts PVC exhaust for flexible installation. Goodman's reputation for reliability backs up the hardware here, and contractor familiarity keeps labor costs predictable.
Performance specs reveal solid engineering. The modulating burner prevents short-cycling losses, while the variable-speed ECM blower maintains efficient airflow across the 2,000 CFM maximum range. Cooling arrives via a 57,000 BTU, two-stage scroll compressor delivering 18 SEER2 efficiency with R410A refrigerant. The 3/8-inch liquid line and 7/8-inch suction line are properly sized for heat transfer. Electrically, the unit demands 208/230V single-phase at 36.7 to 60 amps, typical for residential installs. These numbers translate to lower heating bills without premium equipment cost.
Pros & Cons
Pros
- 97% AFUE furnace efficiency, among the best available for gas heating and meaningful annual fuel savings
- Modulating burner with variable-speed ECM blower adjusts output smoothly, reducing cycling losses and improving comfort
- Two-stage scroll compressor with 18 SEER2 cooling keeps summer utility bills reasonable for a 5-ton unit
- Durable 10-year warranty with online registration covers both furnace and coil for full system protection
- PVC exhaust capability simplifies installation in tight spaces or finished basements where metal venting is problematic
Cons
- 18 SEER2 cooling is solid but not cutting-edge; high-efficiency competitors reach 20+ SEER2 with premium pricing
- 74 dB noise level is acceptable but noticeably louder than premium models operating at lower decibels
- Not Energy Star certified, which may disqualify buyers seeking government rebates or green home certifications
Who Should Buy
Best For
Cold-climate homeowners who heat 7+ months annually and prioritize furnace efficiency over cooling performance. Contractors installing downflow units in basements or crawlspaces appreciate the compact 21-inch footprint and flexible PVC exhaust.
Consider Alternatives If
Buyers in hot climates where AC runs year-round should consider higher-SEER systems, and those needing Energy Star certification must look elsewhere.
Installation
The downflow configuration and compact dimensions simplify basement or crawlspace installation. PVC exhaust avoids masonry venting requirements that complicate retrofits. The modulating furnace and variable blower require proper combustion air supply and ductwork balancing to perform optimally. Technicians familiar with Goodman equipment report straightforward commissioning. AHRI Certificate 7424272 confirms the coil and furnace are matched for rated capacity, reducing field troubleshooting risk.
Warranty & Reliability
Ten-year coverage with online registration protects against defective parts and workmanship. The evaporator coil receives dedicated warranty documentation, a plus for avoiding refrigerant charge disputes. Registration is mandatory for the full term, so buyers must complete it immediately after installation. This warranty is solid but not extended, unlike premium brands offering 12 to 20-year terms.
